Below is the 21-30 segment of the Hockey's Future NHL Team Rankings. The teams are ranked in terms of the quality of their overall prospect pool as voted on by members of the HF staff. For reference, just the top five prospects for each club are listed. To be eligible, a prospect must meet HF's prospect criteria. The rankings are done twice a year, with this ranking meant to represent the state of the prospect pools in the early stages of the 2013-14 season.
